I would think ideally a 1/4" (6.35mm) capacity keyless chuck on the end of a
middle size screw driver would be ideal for this sort of work. Somebody
must have made one already. Maybe a 3/8 or 1/2 would be handy, but I
usually find myself dealing with this on the smaller bits and reamers.

I know them as a pin vise.

Try this search for some examples:

Watch their suggestions along the edges while clicking on a few. That
search doesn't find all they have to offer...

Funny you should bring this up. Just ordered this one:

No particular reason, just handy to have around. I've had a smaller one
for years with small drill bit storage in the handle. Its got a sewing
machine needle chucked in it though, so handy that I just wrote than
one off for other stuff
